“Can I tell you why I was laughing? Basically there were all these big inflatable bouncy black balls that are bouncing around in the crowd on the finale bit. Ariana Grande comes up and stands up next to me and just looks at me and goes, ‘I love big black balls’.”

“My theme for the song is when you have a sort of first relationship or second relationship and you’re young and that relationship ends – you’re so bitter about it and so angry. I feel like you get to 24 or 25, maybe younger if you’re a bit more mature, and you look at your exes in relationships and you’re just like ‘She actually looks a lot happier than when she was with me.‘ But I remember the first girl I was with – that the first and most of the second album were about – I was with from school, and I remember the guy she was with, meeting him one day and being like, ‘He’s so much more suited to her than I ever was.’ And seeing them together, we never looked like that. We were never that sort of couple, never that happy.”
